The first generation Aurora was sold from 1995 to 1998. The only engine sold with this car was the L47 V8. This engine is based on the popular Northstar V8 used in Cadillacs. This car was heralded by car critics for its smooth engine power and more so for its build quality and structural integrity. When General Motors tested the car using a "crush-to-failure" machine, a common practice in the auto industry to test rigidity, the Aurora broke the machine. They would eventually test the car using a machine usually used on much larger trucks. The final outcome: a frame twice as strong as required for its class.
These cars did not want to be known as Oldsmobiles. There was no logos or badges from Oldsmobile on the outside of the car.
The second generation Aurora was sold from 2001 to 2003. The original V8 engine was retained, but a new V6 was also offrered. Like other Oldsmobile cars that were being sold in the final days of the Oldsmobile brand, the last 500 were sold as a special edition called the Final 500 Edition. They were all made with maroon red.
The final year 2003 Aurora is by far the rarest. You can buy Aurora's on the used car market, and they still have the strong frame and luxury features you'd expect from a modern luxury car. You can buy them for even cheaper than your local used market by using eBay, where you can also buy parts.
